FOC implementation based on high priority interrupts for sure will be faster and can save some processor bandwidth. It makes sense for FOC sensorless controllers (eg. ESC) and allows the highest motor performance for given hardware. But this requires handling entire FOC logic on the kernel side wh

Hello Mateusz, I have tried to remove USB CDCACM RX thread, and the problem is remains, so the USB CDCACM RX thread do not related to the problem. the latest measure result is as follows: FOC control thread executed time 48~58us and sometimes 68us FOC control thread execute period is 104~124us

CAN FD - Baud-Rate Settings

Dear all, I'm working on CAN-FD on SAME70Q21*A*. My tools claim a wrong checksum. Therefore I suspect bittiming. Has anybody a working config or can give me a link or tutorial how to set those settings (never saw those segs for the fast data part): [image: image.png] Regards, Simon -- Hard- a
